Biosimilar interleukins are biosimilar products corresponding to interleukins that are naturally produced by leukocytes, or white blood cells, in the body. Interleukins play a key role in regulating immune responses. Laboratory-manufactured interleukins are used as biological response modifiers to enhance immune function, particularly in cancer therapy.
The main types of biosimilar interleukins include IL-17, IL-23, IL-1, IL-5, IL-6, and others. Interleukin-17 belongs to a pro-inflammatory cystine knot cytokine family and is produced by a subset of T helper cells known as T helper 17 cells in response to stimulation by IL-23. These biosimilar interleukins are used for applications such as psoriasis, psoriatic arthritis, rheumatoid arthritis, asthma, inflammatory bowel disease (IBD), and others, and are distributed through channels including hospital pharmacies, online pharmacies, retail pharmacies, clinics, and research institutes.
Tariffs have impacted the biosimilar interleukins market by increasing the cost of imported biologic raw materials, cell culture media, and manufacturing equipment, leading to higher production costs. Hospital pharmacies and retail pharmacies in regions such as North America and Europe are most affected due to reliance on cross-border supply chains. Asia-Pacific manufacturers also face pricing pressures from export tariffs. However, tariffs have encouraged local biologics manufacturing, capacity expansion, and investment in domestic biosimilar production, supporting long-term market sustainability.
The biosimilar interleukins market research report is one of a series of new reports from The Business Research Company that provides biosimilar interleukins market statistics, including biosimilar interleukins industry global market size, regional shares, competitors with a biosimilar interleukins market share, detailed biosimilar interleukins market segments, market trends and opportunities, and any further data you may need to thrive in the biosimilar interleukins industry. This biosimilar interleukins market research report delivers a complete perspective of everything you need, with an in-depth analysis of the current and future scenario of the industry.
The biosimilar interleukins market size has grown exponentially in recent years. It will grow from $7.52 billion in 2025 to $10.54 billion in 2026 at a compound annual growth rate (CAGR) of 40.2%. The growth in the historic period can be attributed to high cost of originator interleukin biologics, increasing prevalence of autoimmune and inflammatory diseases, growing burden of rheumatoid arthritis and psoriasis, limited patient access to biologic therapies, rising awareness of biologics in immune modulation.
The biosimilar interleukins market size is expected to see exponential growth in the next few years. It will grow to $41.22 billion in 2030 at a compound annual growth rate (CAGR) of 40.6%. The growth in the forecast period can be attributed to patent expirations of branded interleukins, expansion of biosimilar clinical pipelines, increasing physician acceptance of biosimilars, supportive government policies for biosimilar use, rising demand for affordable biologic cancer and immunology treatments. Major trends in the forecast period include rising adoption of biosimilar interleukins in autoimmune disease treatment, increasing demand for cost-effective alternatives to originator biologics, expansion of biosimilar approvals across multiple indications, growing use of interleukins in chronic inflammatory disorders, strengthening regulatory frameworks supporting biosimilar adoption.
The rising prevalence of autoimmune diseases such as psoriasis and rheumatoid arthritis is expected to support the growth of the interleukin biosimilars market during the forecast period. Autoimmune diseases are conditions in which the immune system is unable to differentiate between healthy cells and harmful agents, leading to immune attacks on the body's own tissues. Biologic therapies, including anti-interleukin antibodies, have demonstrated strong clinical effectiveness by regulating immune cell behavior and influencing cell proliferation, activation, and migration. For example, in February 2024, according to reports released by the National Institutes of Health (NIH), a US-based biomedical research agency, the global incidence and prevalence of autoimmune diseases are increasing annually at estimated rates of 19.1% and 12.5%, respectively. As a result, the growing burden of autoimmune diseases is increasing demand for interleukin biosimilars and is expected to drive market growth.
Major companies operating in the interleukin biosimilars market are developing innovative products, such as Tofidence (tocilizumab-bavi), to enhance their market position and profitability. Tofidence is a monoclonal antibody that binds to interleukin-6 receptors and is used in the treatment of several inflammatory autoimmune disorders. For instance, in September 2023, Biogen Inc., a US-based biotechnology company, received approval from the US Food and Drug Administration for Tofidence as the first biosimilar to Genentech's Actemra (tocilizumab). The drug is administered via intravenous infusion and is approved for treating severely active rheumatoid arthritis, polyarticular juvenile idiopathic arthritis, and systemic juvenile idiopathic arthritis.
In August 2025, Bio-Thera Solutions, a China-based biopharmaceutical company, expanded its biosimilars partnership with STADA Arzneimittel to include tocilizumab. This extension is intended to strengthen the companies' biosimilar portfolios, improve access to affordable immunology therapies, and support wider global distribution of high-quality biologic alternatives. STADA Arzneimittel is a Germany-based pharmaceutical company specializing in high-value generics, biosimilars, and consumer healthcare products.
